NGH 17cc Petrol Engine.

First run today, running on 20% for the break in and propped down, fired up first time and ran as sweet as a nut, throttlings good, pretty clean considering the mix, NGH wrap around pitts exhaust from Just Engines, think It'll be o.k for noise when propped up.

Be interesting to know your noise readings once you've got it ready to fly, thanks.

Yep 20% for break in, follow the manual, then 30% - 33% for flying, another run and I'll fly it next, revs not going up n down, pick up is crisp, not touched needles, If it continues to perform like this I'll be very happy.

20% is not the same as 20:1 fuel ratio which works out to 5% oil content as per the instructions and when run in you can reduce the oil to 4%which is 25:1 so please be carfull

Hi John.May I ask what the model is that you are fitting your NGH17 engine into. I have an unused 17 that I have fitted a venturi on to. It apparently improves the running of the engine and stops fuel being sucked out of the carby,especially when fitted inverted. I have been trying to find a suitable model for my engine,and I like the look of yours.

Hi again John Stones 1. I received my Funky Cub on Saturday last from SMC Models. As I said,only £219 free post.

The manual that came with the engine quotes a propeller size of 13x8---15x8 that is for a 2 bladed prob. I would like a bit more ground clearance, so I was going to go for a 3 bladed prop. Any advice what size and pitch of prop would suit the NGH 17 engine.

It gives a range Anthony, the prop used depends on the model and what you want from the Engine, I honestly couldn't tell you if a 3 bladed prop suits, It's suck it n see I would think. I can tell you even with a 15 inch prop on, there's plenty of clearance. I will be going with a 15x6 most likely 15x8 if it noisy, ask away if I can help, I will. Gave it a few more runs, starts very easy.
